To all whom it may concern:

Be it known that I, FRANK KOENIG- KRAMER, a citizen of the UnitedStates, residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements inTreating-Tables, of which the following is a specification.

My invention relates to improvements in treating tables. One of itsobjects 1s to provide an improved vertically adjustable table, therespective top sections of which are independently supported andadjustable upon the vertically adjustable section of its supportingcolumn. Another object is to provide a table having independentlymovable and adjustable top sections and 1mproved mechanism to movablysupport and adjust the respective top sections. Another object is toprovide a table having a top section with a variety of differentmovements, and means to enable said several movements to be employedseparately or conjointly. Another object is to provide a table having amovable section yieldingly sup ported upon a vertically adjustablestandard and improved means to vary and adjust the tension thereof.Another object is to provide improved means to tension and limit themovements of the movable top sections to restrain or to preventexcessive or too free a movement thereof. My invention also com prisescertain details of form, combination, and arrangement all of which willbe fully set forth in the description of the accompanying drawings inwhich:

Fig. 17 is a top plan of the head F and parts mounted thereon.

The accompanying illustrations represent the preferred embodiment of myinvention in which A represents a base, having extensions a. B a columnvertically ad ustable relative to said base, and C, D, and E independenttable top sections each supported upon and adjustable relative to saidcolumn B.

The column B may be adjusted relative to the base A in any desiredmanner. I have illustrated said column as a piston seated in a verticalcylinder in the base A, relative to which it is vertically adjustablehydraulically by reciprocating the handle, 2 of a hydraulic pumpcontained within sald piston. A brake shoe 3 forced against the outerface of the piston by means of a set screw 4: threaded through an ear ofthe base A serves to rigidly lock the piston in its adjusted position toretain the piston in place for long periods.

At the upper end of the piston B is an extended 0r enlarged head Fhaving a depending arm 5 which is bored to receive a vertical shaft 6,and is provided with a rectangular bar 7 which seats in a correspondinggroove in the side of the base A to prevent the column B and head F fromturning or rotating relative to the base A. At the upper end of theshaft 6 is a head or block 8 rigidly locked to said shaft and restingupon the upper face of the head F. At the lower end shaft 6 is providedwith a collar 9 held in place by a set screw 10 threaded through an ear11 of the arm 5 and into said collar and in position for the point ofsaid set screw to selectively engage one or more holes in said shaft 6to lock the shaft to adjusted position and against rotation. Below thecollar 9 is a block or collar 12 rigidly locked to shaft 6 by a setscrew.

The table top section C is designed to support thehead and shoulders ofthe patient, and is pivotally attached upon a horizontal axis at 14 onopposite sides to arms 15 of the head F. Bars 16 are attached toa-projection 17 of the head F and extend outwardly parallel to eachother beneath the section C. At the outer end of said bars-l6 is apivotally supported gripping head or stirrup 18 which has a recessthrough whichpasses a bar 19 which is hinged at 20 to the under side ofthe section C. The bar 19 has stops 21 to limit its movement through thestirrup 18 and said stirrup has a block of hardened steel 22 which tendsby the gravity action of the stirrup 18 to automatically grip the bar 19and prevent it from passing downwardly through the stirrup. If desired aspring 24 may be employed instead of relyingupon gravity to'cause'the'stirrup to grip the'bar 19. The bar 19 moves freely in the oppositedirection through the stirrup. I also preferably provide a series ofperforations in the bar 19 set at regular intervals apart, and by meansof which and a pin inserted through one of said perforations above theblock 22 said bar 19 may-bepe'rmanently locked to any desired position.For ordinary adjustments of the section 0 upon its centers 14, theoperator may lift the outer end of section C to any desired position ofinclination when the'block 22 will automatically grip the bar 19 andhold the section in place, or if'it is desired to move section 0 to aposition of less inclination the operator takes a hold of the outer endof section 0 with both hands and by pressing on the lever 25 of thestirrup with his knee releases the engagement-of block 22 with bar 19and lowers the section C to the desired position when the block 22automatically reengages bar 19.

The table top section D is designed to support the hips of the patientand to have a pivotal movement upon a vertical axis or pin 29, and alsoto be inclined or tilted upon a horizontal axis approximately above andintersecting said vertical axis, whereby said section D may be adjustedand held to either a horizontal or an inclined position. The section Dhas downwardly projecting cars 27 by means of which it is pivoted upon ahorizontal axis to the frame 28. The frame 28 has a downwardlyprojecting pin 29 which seats in a recessbored in the up er end of shaft6. The under face of frame28 rests upon the head 8 adjacent to the pin29, and the arm 30 of frame 28 rides'so close to the projecting end 31of head 8 as to engage therewith when section Dis subjected to a heavyweight, therebv preventing the pin 29 being bent or unduly strained.

A crank shaft 32 is journaled to the frame 28 with one end 33.projecting to be grasped by the operator while the crank pin 34 at theother end of shaft 32 engages and travels in a slot 35 formed betweenthe angle plate 36 and the flat plate 37. Said plates are held inposition to the underside of section D by means of screws 33 on theshanks of which are springs 39 which yieldingly hold the plate 37inengagement with the crank pin 34. In the position of the crank indicatedin Fig. 11 and in full line Fig. 12 the section D is inclined, while inthe position Fig. 10 and dotted lines Fig. 12 the section Dis in ahorizontal position. There is suflicient frictional engagement betweenthe plates 36 and 37 and crank pin 34 to cause the shaft 32 to retainwhichever position it is adjusted to.

The table top section E is supported upon a frame 40 relative to whichit is adjustable endwise, and also pivotally. with the axis of itsadjusting screw as a center. The frame 40 is pivotally supported upon ahorizontal axis at 41 relative to the head 8 and yieldingly tensioned soas to secure a reciprocating or rocking motion of the section E aboutsaid axis 41. A screw threaded rod 42 is journaled in brackets 43 and 44attached to the section E and engages the central threaded boss of thecross bar 45 of the frame 40 to feed the section longitudinally of theframe 40, said screw being rotated by. hand by means of the crank 46. Ashaft47 concentric with the screw rod 42 is j ournaled at oneend in thebracket 44 and at the opposite end in a bracket 48 also attached to-thesection E. Cross bars 49 and 50 are rigidly secured-by set screws to theshaft 47 between the brackets 44 and 48 so as to rock with said shaft inits bearings The longitudinal rods of frame 40 pass through eyes in thecross bars 49 and 50 and slide longitudinally therein when the sectionis adjusted by the screw rod Rubber buffers or stops 51, carried bybracket 48, engage the ends of the cross bar 50 and noiselessly limitthe rocking movement of the shaft 47. The bracket 44 is provided with anannular projection 52 which is en aged by a shoe 53 held in engagementtherewith by a set screw 54 carried by the crossbar 49, said shoeserving to prevent the shaft 47 from rocking too freely in. its bearingsw hich action may be varied byv adjusting the set screw 54. A hand lever55 is pivotally attached to section E at 56 and is provided withprojecting arms 57 which may be shifted into and out ofengagementwiththe cross bar 49 to lock the section Etoa' horizontal position above'andrelative to the frame 40, by preventing rocking motionof the shaft 47and its cross bars 49 and 50.

The rotary movement of the shaft 6 in its bearing 5 provides forswinging the section E in horizontal planes backward and forward, andthis movement is preferably limited and said section returnedautomatically to a central ornormal position by means of a spring 60attached at one end to a link 64 pivoted to the projection 31 of thehead 8 and at the opposite end to a threaded eye-bar 61 adjustablyconnected by a nut 62 to a bracket 63 attached to the projection 17 ofthe head F, whereby any desired tension on spring 60 may be secured.

In order to adjustably tension the movement of the table section E andits frame 40 upon the center 41, and to lock said section E againstmovement upon said section I provide a frame 68 substantially parallelwith frame 40 and pivotally attached at 66 to the collar 12 carried bythe shaft 6. A. spring shackle 67 is pivoted to a carriage 68 whichrides on the frame 65, and is adjustable thereon by means of the screwrod 69. The screw rod is rotatably mounted in a block 70 pivotallyattached at 70 to the side bars of frame 65, and is adjusted by means ofa hand wheel or crank 71. Another spring shackle 7 2 is pivotallyattached at 7 3 to'the head 8. Said spring shackles, see Fig. 6, areprovided with a plurality of eyes to be engaged by a plurality of coiledsprings 74 which springs tend to pull the frame 65 upwardly toward theframe 40. A threaded eye-bar 75 is pivoted upon a cross rod 76 of theframe 40, and a nut 77 threaded thereto engages a tube 78, see Fig. 7,which tube has forked arms 79 at its lower end pivotally connected tothe center 70 of frame 65, thereby enabling the nut 77 to be adjusted toforce the frames 40 and 65 apart against the action of the springs 74,and also serving to transmit the tension of springs 74 into forcetending to lift and support the frame 40 and parts carried thereby.Downward movement of the nut 77 on the bar 75 tends to lift t 1e outerend of section E to a higher point, or to elongate the springs 74, sothat adjustment of the nut 77 may be made to substantiallycounterbalance variable weights to be supported by the section E. Themovement of the carriage 68 to or from the base A also serves toincrease or diminish the tension of the springs and to increase theleverage of the springs 74 tending to lift the frame 65, and through therod 75 the frame 40 and section E, thus providing an increased range ofcounter-weighting support for the section E.

As illustrated in Fig. 7 the lower end of rod 75 is guided in the tube78, with the nut 77 and tube 78 only in a thrust engagement leaving thesection E free to be lifted still farther by hand with the nut 77 out ofcontact with the tube 78. In the modification Fig. 8, however, an innersleeve 80 is rotatably mounted in the tube 78 and the rod 75' isthreaded to said sleeve 80, which may be turned by its hand. wheel 81 tofeed the rod up or down within the sleeve 80, while the nut 82 isemployed as a stop or lock nut.

In order to lock the section E against pivotal movement upon the center41 I provide a depending arm which is pivoted upon a cross-bar 19 offrame 40 and its lower end interposed between one of the bars of frame65 and a strap 92 locked at one end to said bar 65 upon the bolt 70. Atthe opposite end the strap 99 is seated. over a threaded stud 93, whichis fitted with a clamping nut 94, by means of which the free end of arm90 is clamped to frame 65 to lock section E in place. When unlocked thearm 90 slides freely up and down between the frame 65 and strap 92.

When the supporting members 75, 77, and 78 illustrated in Fig. 7 areemployed in connection with the locking member 90 to transmit theresilient strain of spring 74 from the arm 65 to the auxiliary topsection E, the member 90 forms a non-extensible connection betweenmembers 40 and 65, and hence with members 40, 65, and 6, forms arectangular frame-work, which prevents the top E and arm 65 from risingabove a predetermined position, depending upon the point at which member90 is clamped to member 65. If however force downwardly is applied tothe top E, sufficient to overcome the tension of spring 74, whichvariable by adjustment; the force will be transmitted from the top Ethrough member 90 to arm 65, the members 7 5 and 77 will separatetelescopically from member 78 sufficiently to enable the top E and arm65 to be yieldingly depressed to a limited extent, and when thedownwardly directed force on the top E is released, the top E and arm 65will return to but not above the predetermined point. Adjustment of thecarriage 68 will predetermine the amount of force downwardly on the topE which will be necessary to effect this downwardly yield ing movementof the top section E.

The top section D is locked against rotation upon its center 29 whendesired by means of a bar 95 sliding endwise relative to and across thetop of head F. Said bar is actuated by a pivoted hand lever 96, and hasupwardly projecting lugs 97 and 98, one of which engages a notch 99 inone arm of the frame 28, while the other engages under the opposite armof frame .28, and in the locked position both serve to support thesection D and to relieve the shaf 99 from strain.

My improved table is thus capable of being adjusted to secure a softpliable flexi ble movement of the table section E. and adjustmentthereof to correspond to the weight of the different patients. Saidsection has an endwise movement, a rocking movement and a pivotalmovement, each of which may be locked or used independently of or inconjunction with the section E, and its separate adjustments employedindependently and locked when not required. All the table top sectionsare also supported upon and adjustable relative to a common standard orsupport Which is itself vertically adjustable to secure the desiredposition of the patient verticallv.

When the top section D is locked to the head F it becomes, in effect orfor practical purposes, a part of the section C. When the section D isunlocked from the head F and the forward or adjacent edge of section Eis practically in engagement Withthe straight edge of section D, thesections D and E move in unison upon the shaft 6 as a center practicallyas a single section, While When section D is free to move and section Eis adjusted to leave a considerable gap between sections D and E each ofthe three sections are practically free and independent of each other.
